Answer;
Activation synthesis model of dreaming
Explanation;
-The activation-synthesis model suggests that dreams are caused by the physiological processes of the brain.
-According to activation synthesis hypothesis of dreaming, dreams are the brain's attempt to make sense of the random firing of the brain cells during REM sleep.
People impose meaning on random mental activity. This is a theory that dreams result from the brain's attempt to make sense of random neural signals that fire during sleep.
Answer:
In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.
In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.
